To all whom it may concern: )3

Be it lmown that I, WALENTY Kamonu, a sub ect of the Emperor of Germany, re-=,=" siding at Grafton, county of Lorain, and" State of Ohio, have invented certain new and useful Improvements in Window-Op crating Devices, of which the following is a specification. This inventionrelates to improvements for raising and lowering window sashes, and

has as its special object the provision of means whereby, when the lower sash is raised, the upper sash will be correspondingly lowered automatically.

This object is accomplished by the novel construction and combination of parts hereinafter described and shown in the accompanying drawings, forming a material part of this disclosure, and in whichv Figure 1 is a front elevational view of a window showing the application of the invention.

Fig. 2 is an enlarged front elevational 'view of one of the operating devices.

Fig. 3 is a vertical sectional view taken through a conventional type of window,

showing the two sashes in a closed position.

Fig. 4 is a similar view showing a modified form of construction of closing means. Fig. 5 is a fragmentary perspective view showing an upper sash, an Fig. 6 is a similar fragmentary perspective view showing the lower sash.

In the drawings, the numeral 10 indicates the walls of a building containin a window frame in which are operativey engaged sashes 11 and-12, respectively upper and lower, the same carrying the usual glass or transparent panels 14.

Attached upon opposite sides of the window frame are plates 18, by means of screws, nails or like fastenings, passing through a plurality of openings 19 formed through the plate, which is substantially rectangular in contour with rounded corners.

Secured pivotally at the center of the plates, by the pins 20, are pinions 21, and meshing therewith are spur gears 22 and 23, rotatably mounted upon pins 24., the gears 22 meshing with racks 25 fixedly secured upon the outer sides of the window sash loy screws or like fastenings 26, the upper ends of the racks having extending stops or projections 27, which when coming in contact with the teeth of the gear, prevent further movement.

Similarly, thegears 23 are in mesh with the racks 30, held by the screws 31 and having like projections 32 contactable with the teeth of the gears 23. m From the foregoing it will be clearly apparent that when the lower sash 12 is raised, the upper sash 11 is correspondingly lowcred until they are in register, at which time the extremities of the racks and their projections 27 and 32 respectively, come in contact with their meshing gears.

In the modification, shown in' Fig. i, the

gears 22 are in mesh with racks 35, extending longitudinally the entire length of the upper window sash, while the gears 23 are engagedwith the teeth of raclps 36 secured upon the lower sash and extending its full length, therefore permitting the windows to be operated to their full extent.

Having thus described my invention what I claim as new and desire to secure by Letters Patent isy In a window sash operating device, the combination with a window frame, an upper and a lower, sash slidably engaged therein,

racks secured upon each side of both sashes,

said racks faclng each other, rectangular perforated plates having rounded corners attached to opposite sides of the window frame, pinions pivoted to the center of said plates, and spur gears engageable with each of said racks and with said pinions, means for communicating motion'between said gears, and stops projecting at the upper ends of said racks for limiting the motion of said window frames.

In testimony whereof I have aiiixed my signature.

WALENTY KALIOKI.
